Application filed December 8, 1899. Serial No. 739,713

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters marked thereon, which form a part of this specification.

This invention relates to spiral cottons'pindles and wipers consisting of spiral cotton-picking spindles provided with hair or yielding picking-points and spiral tubes or tubular wiping devices.

The primal objectof my invention is to provide a spiral wiper device for a spiral cotton-picking spindle.

The second object is to arrange said spiral wiper as a tube or tubular device for the passage and rotation of a spirally-twisted cotton picking spindle.

The third object is to provide a spirallytwisted cotton-picking spindle with hair or yielding picking-points and to wipe said spindle by screwing it through a tubular spiral wiper device.

These several objects are obtained by the devices illustrated in the accompanying drawings, in which Figure 1 is a sectional side or plan view of my invention. Fig. 2 is an end view of the spiral wiper-piece in Fig. 1. Fig. 3 is an end view of the spiral wiper-pieces fastened by screws to a post or other support. Fig. 4 is a section or detail plan or side View of a modification of Fig. 1. Fig. 5 is a perspective view of the spiral tubular wiper-piece. Fig. 6 is a perspective view of a flat tube for forming the spiral wiper-piece by twisting said fiat tube into a spiral tube, as indicated by the dotted lines. Fig. 7 is a perspective view of a fiat piece of sheet metal to be twisted spirally, as indicated by the dottedlines. Fig. 8 is a perspective view of Fig. 7 as spirally twisted. Fig. 9 is a side or plan view of a spoke, arm, or support provided with a hole in which two pieces, twisted as in Fig. 8, are inserted and fastened by their heels to said support, thus arranged and adapted to form the preferred form of constructing the tubular spiral wiper device. Fig. 10 is a side or plan view of a detail of the support, the holethereof being provided with a tube in which the two twisted spiral pieces are secured as a modification of Fig. 9. Fig.

11 is an end view showing the point N of a single spiral twisted piece which is used to form the spiral tubular wiper device. Fig. 12 is an end view showing the spiral twisted piece and its point N covered by a slotted wiper-piece.

Similar letters of reference indicate the same parts in the drawings and the several figures thereof.

Referring by letter to the accompanying drawings, the cotton-picking spindle consists of two fiat flexible steel strips A, twisted together spirally and provided with haircloth sandwiched between them and forming hairpicking points B all along the spiral edges, forming a flexible spring-like spiral or screw with brush edges, the two bands A being twisted together at the point C, the other end being riveted in a slotted collar or stud-shaft D, journaled to rotate in a metallic arm or bar E and provided with a roller or gear F, whereby the said cotton-picking spindle is caused to rotate on its own axis, screwing its way in and out of the spiral wiper-tube G, which tube is twisted spirally to conform to the threads of the spindle, so as to form a spiral tube-nut therefor, and provided with ears or wing-pieces H, the central orifice I being arranged and adapted to only freely pass the said cotton-picking spindle spirally through said wiper-piece G, the said wiperpiece being fastened by screws or nails driven through holes in the wings H and into the wood spoke or support J, all of which is fully illustrated by Figs. 1, 2, 3, and 5. The said cotton-picking spindle is forced to screw its way in and out through the spiral wiperpiece, thereby rotating on its own axis by means of the bar E being pushed toward and away from the post, spoke, or support J. The said rotation of said spindle may be further increased by rotating the pinion F and arranging the wiper-tube G to also rotate in the post J; but the preferred construction is as in Fig. 4, wherein the gear or pinion F is not used, a simple collar K being substituted therefor and the said rotation of the spindle being caused solely by the bar E being pushed to and from the post J, thereby causing the said spindle to screw in and out through the spiral wiper-piece G. The said movements being more fully illustrated and described in my patent applications Serial Nos. 681,148 and 730,468. It will be understood that the said tubular wiping device may be formed in one or more pieces by casting, twisting, or stamping with dies and that in Figs. 1, 2, 3, 5, and 6 the wiper is illustrated as a spirallytwisted tube which may be secured to the bar J in a hole L formed therein or otherwise.

In Figs. 7, 8, and 9 the tubular wiper device is illustrated as formed of two sheetmetal pieces, as in Fig. 7, twisted spirally, as in Fig. 8, and in Fig. 9 inserted in a hole L through the bar J, being fastened on both sides to the bar J by screws or nails through the heels or wings H, and by this arrangement forming a spiral wiping device for spiral cotton-picking spindles. In Fig. 10 in the hole L through the block J is driven a light tube M, through which is inserted the two spirally-twisted pieces, as in Fig. 9, and likewise fastened to the bar J. The object of these different views and modifications is to fully illustrate and describe that my invention broadly consists of a tubular spiral wiper device formed of one or more pieces arranged and adapted to wipe the gathered cotton from spiral cotton-picking spindles.

In the operation of my invention the cot ton-picking spindle is pushed or screwed through the tubular wiper device and, proj ecting therefrominto the co tton-plants, picks the cotton therefrom by winding it upon its projecting body, which being drawn back through the wiper device the gathered cotton is wiped ofi, inasmuch as there is no space for the pasage of the cotton into the wiper device, the passage therein being filled by the spindle itself, or sufiiciently so to bar the entrance of the cotton. The wipin off of the cotton is also facilitated by the halr or yielding picking points of the spindle bending or yielding forward, and thus more easily permittim of the wiping of the cotton from this form of spindle than would be possible in any rigid toothed spindle, and for this reason I desire to claim the said spindle in combination with said wiping device, as it would not be so practical in other forms of spindles.

It will be further understood that a single spirally-twisted piece, as in Fig. 8, may be inserted in the tube M (shown in Fig. 10) or in the hole L of the post J, as in Fig. 11, so as'to thereby form a spiral tubular wiper device by the use of only one piece, which is secured b its heel H to the post, as indicated by dotted lines, Fig. 11, which is a front or end view showing the point N of the spiral twisted piece secured in the hole L of the post J. This point N may be'made to project, and after the heel H is fastened to the post J the said point N may be then bent to form another heel and also fastened to the post J, thereby securing the spiral pieces at both ends to said post J,

making it thus impossible to detach the said spiral twisted piece without first bending up again the point N into its former straight position. The said point N may then be covered by a slotted washer O, as in Fig. 12, or the said spiral piece be inserted in a tube M, as in Fig. 10, in which the picking-spindle is screwed in and out to form a spiral tubular wiping-piece.
